It is only a trickle so far, and not nearly enough to constitute a

troubled Spanish banks reflect a broader fear that the country’s

fail and cannot be supported by the government. In a worst case, some
even worry their money will be worth substantially less if Spain is
forced to leave the euro currency zone and re-adopt its old currency, the peseta.
